Event Description

Take on the length of the Caltrain main line from San Francisco to San Jose in this road ultra-endurance challenge.

Ultra rail is a unique format combining the strain of an unsupported road ultra with the strategic requirements of a self-navigation challenge.

Our challenges vary from a mere 30-something miles to over 80 miles, run almost entirely across sprawling urban metroplexes. Dallas to Fort Worth, DC to Baltimore, LA to San Bernardino are just a few examples of challenges we offer.

To put your name on the board, you’ll have to research your own route from start to finish, complete your challenge in under the challenge time limit and submit your GPS results for approval within 28 days of signing up.
